SUSE-SA:2006:014: gpg

high Nessus Plugin ID 21093

Synopsis

The remote host is missing a vendor-supplied security patch

Description

The remote host is missing the patch for the advisory SUSE-SA:2006:014 (gpg).


The GNU Privacy Guard (GPG) allows crafting a message which could check out correct using '--verify', but would extract a different, potentially malicious content when using '-o --batch'.

The reason for this is that a .gpg or .asc file can contain multiple plain text and signature streams and the handling of these streams was only possible when correctly following the gpg state.

The gpg '--verify' option has been changed to be way more strict than before and fail on files with multiple signatures/blocks to mitigate the problem of doing the common --verify checks and -o extraction.

This problem could be used by an attacker to remotely execute code by using handcrafted YaST Online Patch files put onto a compromised YOU mirror server and waiting for the user to run YOU.

This problem is tracked by the Mitre CVE ID CVE-2006-0049.

This is a different issue than the gpg signature checking problem for
